Halotestin tablets

Fluoxymesterone, sold under the brand names Halotestin and Ultandren among others, is a synthetic, orally active androgenic-anabolic steroid (AAS) and a 17α-alkylated derivative of testosterone. While there are legitimate medical uses of fluoxymesterone, it is also abused, leading to the development of analytical techniques by which fluoxymesterone doping can be identified.
